Damaging Winds in Maryland, April 19, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
626 PM EDT FRI APR 19 2013

.SYNOPSIS...
A STRONG COLD FRONT WILL APPROACH FROM THE WEST AND CROSS OUR REGION
DURING THE EVENING AND OVERNIGHT HOURS. LATE SATURDAY AND THROUGH
SUNDAY, AN AREA OF HIGH PRESSURE WILL BUILD TO OUR NORTH. THIS HIGH
PRESSURE WILL SHIFT EASTWARD TO THE CANADIAN MARITIMES MONDAY AS A
WEAK DISTURBANCE TAKES SHAPE ALONG THE SOUTHEAST SEABOARD. THIS
SYSTEM WILL REMAIN OFFSHORE AS IT PASSES BY TO OUR EAST TUESDAY. FOR
MIDWEEK, A COLD FRONT IS FORECAST TO TRACK THROUGH THE REGION FROM
WEDNESDAY INTO THURSDAY, FOLLOWED BY HIGH PRESSURE BUILDING OVER THE
MID ATLANTIC ON FRIDAY.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
TWO WATCHES IN EFFECT AND WILL CONTINUE. SQUALL LINE DEVELOPING
ATTM ACROSS E/CNTRL PA AND IT WILL MOVE EWRD THIS EVENING. THE
BEST LTG ACTIVITY REMAINS WELL SOUTH...BUT STILL SOME POTENTIAL
FOR LTG TO DEVELOP THIS EVENING WITH THE ACTIVITY TO THE WEST.
GUSTY WINDS POSSIBLE WITH THE ACTIVITY WHEN IT ARRIVES HERE
THROUGH 900 PM.

AM EXPECTING 0.5 TO 1.5 INCHES IN 3 HOURS TONIGHT WITH A LEAD
SQUALL LINE THEN POST SQLINE RAINS WITH ISOLATED EMBEDDED THUNDER.

CLEARING FM W TO E OVERNIGHT...MAYBE SPOT PATCHY FOG IN THE
COUNTRYSIDE BUT ENOUGH WIND SHOULD PREVENT THIS. MIGHT HAVE A
BETTER CHC FOR FOG THIS EVENING IN THE SLY FLOW ALONG THE COASTS.

TEMPS/WINDS AND POPS ARE BASICALLY BLENDED 12Z/19 NCEP GUIDANCE
WITH SREF BLENDED INTO THE POPS.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
SATURDAY...MOSTLY SUNNY START...VARIABLE CLOUDS EARLY AFTERNOON
THEN MOSTLY SUNNY LATE DA. GUSTY WNW WIND 20 TO 28 KT DURING THE
DAY.

12Z/19 BLENDED NAM/GFS MOS GUIDANCE FOR THE FCST...SIMILAR TO
PRIOR FCST FROM EARLY THIS MORNING.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
THE LONG TERM PERIOD WILL START WITH RELATIVELY QUIET CONDITIONS AS
AN AREA OF HIGH PRESSURE OVER THE MIDWEST STATES SPREADS NORTHEAST
TOWARD THE GREAT LAKES AND OHIO VALLEY FROM SATURDAY NIGHT INTO
EARLY SUNDAY. THIS HIGH PRESSURE WILL THEN CONTINUE TO BUILD OVER
THE NORTHEAST STATES DURING SUNDAY AND WILL PROVIDE FOR QUIET AND
DRY WEATHER ACROSS OUR REGION. OF NOTE DURING THIS TIMEFRAME, MAINLY
CLEAR SKIES AND RELATIVELY LIGHT WINDS WILL ALLOW FOR GOOD RADIATING
CONDITIONS SATURDAY NIGHT AND INTO THE EARLY MORNING SUNDAY. A BLEND
OF MET/MAV GUIDANCE WAS USED FOR MINIMUM TEMPERATURES SATURDAY
NIGHT, WITH OUR FAR NORTHERN ZONES DROPPING INTO THE UPPER 20S AND
LOWER TO MIDDLE 30S EXPECTED ELSEWHERE. WITH THE GROWING SEASON
HAVING STARTED FROM SOUTHEASTERN PA AND CENTRAL NJ DOWN THROUGH OUR
DELMARVA ZONES, FROST AND FREEZE CONDITIONS WILL BE A CONCERN, AND
WE WILL CONTINUE TO MENTION THIS IN OUR HWO PRODUCT.

FROM LATE SUNDAY THROUGH MONDAY, THE AREA OF HIGH PRESSURE IS
FORECAST TO SHIFT EASTWARD FROM THE NORTHEAST STATES TO THE CANADIAN
MARITIMES. IN ADDITION, THERE IS SOMEWHAT BETTER MODEL AGREEMENT
REGARDING A WEAK TROUGH THAT IS PROGGED TO DEVELOP OFF THE COAST OF
THE SOUTHEAST STATES DURING THIS TIMEFRAME. BOTH THE GFS AND ECMWF
SHOW THIS FEATURE SLOWLY ADVANCING NORTHEASTWARD ALONG THE EASTERN
SEABOARD THROUGH MONDAY AND REMAINING OFFSHORE AS IT PASSES BY OUR
REGION TUESDAY. THERE REMAINS SOME UNCERTAINTY WITH REGARDS TO
PRECIP POTENTIAL AS THIS SYSTEM PASSES BY TO OUR EAST MONDAY NIGHT
THROUGH TUESDAY. BOTH MODELS SUGGEST THAT THERE WILL BE ENOUGH WRAP
AROUND MOISTURE TO YIELD SCATTERED SHOWERS FOR THE REGION, WITH THE
BEST CHANCES BEING FOR OUR EASTERN ZONES NEAR THE COAST.

THE NEXT SYSTEM OF CONCERN WILL BE AN AREA OF LOW PRESSURE ADVANCING
FROM AROUND THE GREAT LAKES INTO SOUTHEASTERN CANADA DURING
WEDNESDAY, WITH ITS ASSOCIATED COLD FRONT APPROACHING OUR REGION
FROM THE WEST. THERE CONTINUES TO BE TIMING DIFFERENCES BETWEEN THE
GFS, ECMWF, AND OTHERS REGARDING THE PASSAGE OF THIS COLD FRONT
THROUGH THE MID ATLANTIC REGION. THE GFS IS ON THE EARLY SIDE,
BRINGING THE FRONT THROUGH WEDNESDAY TO WEDNESDAY NIGHT, WITH THE
SLOWER ECMWF TAKING THE FRONT THROUGH THURSDAY MORNING. WITH THIS
UNCERTAINTY REMAINING BETWEEN THE MODELS, WE HAVE MAINTAINED
CONTINUITY FOR THE MOST PART AT THIS EXTENDED TIME RANGE, WITH
HIGHEST PRECIP POTENTIAL CENTERED AROUND WEDNESDAY NIGHT AND CHANCE
POPS IN PLACE DURING THE DAYTIME WEDNESDAY AND THURSDAY. THEREAFTER
FOR THE END OF THE WORK WEEK, THERE IS SOME MODEL AGREEMENT WITH AN
AREA OF HIGH PRESSURE PROGGED TO SPREAD OVER THE MID ATLANTIC STATES
BY FRIDAY.

&&

.MARINE...
GLW CONTINUES AS ISSUED AT 1052 AM: IN THE FACE OF STRONG BL WINDS
AND A PROBABLE EVENING SQLINE OF SORTS THOUGHT IT BEST TO PREPARE
MARINERS FOR GALE GUSTS LATE THIS AFTN OR EVENING. IT MAY VERIFY
JUST SHORT OF OUR 2 HOUR CRITERIA FOR VERIFICATION BUT ATTM...COULDNT
SEE ISSUING AFTER THE FACT SMW'S FOR NON-SHOWER RELATED GUSTS OF
34 KT. SO DISCOMFORT ASIDE ON BEING CERTAIN OF VERIFYING 2 HOURS
OF GALE... SERVICE TOOK PRECEDENT...PREVENTING POTENTIAL MARINE
WEATHER RELATED INCIDENTS.

SEAS 4-5 FEET AT 4 PM...WINDS HAVE GUSTED 22-32 KT BUT AT LEAST
TEMPORARILY DIMINISHED. SEAS SHOULD INCREASE RAPIDLY LATE TODAY OR

AFTER THE GALE WARNING EXPIRES: WSHIFT TO NW TOWARD MIDNIGHT WITH
BRIEF GUSTS 25-30 KT AND THEN WNW G20-30 KT SATURDAY WITH SE
SWELLS-SEAS SUBSIDING SLOWLY.

OUTLOOK...
GOING INTO SATURDAY NIGHT, SUB-SCA CONDITIONS ARE EXPECTED FOR THE
AREA WATERS AS AN AREA OF HIGH PRESSURE WILL BE BUILDING TOWARD THE
REGION. THIS HIGH PRESSURE ULTIMATELY BUILDS TO OUR NORTH OVER THE
NEW ENGLAND STATES DURING SUNDAY, AND WE EXPECT WINDS AND SEAS TO
REMAIN BELOW SCA LEVELS THROUGH THIS PERIOD. SOME WIND GUSTS AROUND
20 KNOTS ARE NOT OUT OF THE QUESTION, HOWEVER. AS THIS HIGH PRESSURE
SHIFTS MORE TOWARD THE CANADIAN MARITIMES ON MONDAY AND A WEAK
DISTURBANCE DEVELOPS ALONG THE SOUTHEAST SEABOARD, THE GRADIENT WILL
TIGHTEN ACROSS OUR WATERS WITH AN EASTERLY FLOW. WIND GUSTS AND SEAS
WILL LIKELY REACH INTO SCA CRITERIA LATE SUNDAY NIGHT INTO MONDAY
AND LAST THROUGH TUESDAY.

&&

.FIRE WEATHER...
WIND AND RH WILL MEET CRITERIA SATURDAY AFTERNOON BUT ONE HAS TO THINK
TONIGHTS RAIN WILL BE ENOUGH TO PREVENT THE NEED FOR AN SPS FOR INCREASED
FIRE DANGER IN NJ AND E PA.
